To all whom it may concern Be it known that I, FRITZ ECKEY, a sub- 'ect of the King of Prussia, residing at wickenham, England, (whose post-oflice address is 2-1 Sidney road, St. MargaretYs, Twickenhain, Middlesex, England,) have invented certain new and useful Improvemcntsin Sash Raising and Lowering Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

This invention consists of improvements in and relating to sliding windows such as those employed in motor cars, railway carriages, and like sliding windows, and particularly the invention consists in improvements in lazy tongs apparatus or mechanism for raisin and lowering such windows.

Hcretoibre lazy tongs apparatus has been proposed, for raising and lowering railway and other carriage windows, in which the lowermost members or levers of the lazy tongs have been fitted to a suitable base plate and said levers connected to a suitable balancin spring or springs the said base plate and springs being mounted at or adjacent to the bottom of the window well in the door or wall of the vehicle, the window glass being mounted on the uppermost members or levers of the lazy tongs. In some of such proposed arrangements an operating handle or knob was provided on the window glass itself, or on the sash in which the window glass is mounted, so that on mov' the window up and down by means of 's'l lii knob or handle. the lazy tongs was respeotively opened-or expanded and closed or collapsed, In other proposed arrangements an operating handle or lever with a connection or connections to the lazy tongs was provided so that by actuating such handle or lever the lazy tongs was opened or expanded and closed or collapsed respectively for raisingand lowering the window, andv further means were provided in connection with such operating handle for locking or holding the window in the desired position for instance either fully open or fully closed, or partially closed and in one such construction it was proposed to ivotallymount a pair of levers on a bar mi way betweenthe bottom of the door and the lock rail and to connect the lower ends of such levers to the lower members o,f the lazy tongs and the upper ends to the said operating lever or handle. Such previously .proposed constructions and or rangementsare, however, objectionable in several respects. For instance the pivoting of-the lowermost levers or members of the lazy tongs on a base plate at the bottom of the window well in the door or wall of the vehicle renders'it a matter of considerable difliculty and increased cost for fitting up the apparatus and especially so in the case of applying such apparatus to existing -vehicles. Further the apparatus is difiicult of access should repair be necessary. Another objection to such previously proposed apparatus is that the window glassfi-or the sash in which the window glass is mounted-be ing connected to the uppermost member or levers of the lazy tongs, the said lazy tongs occupies so much space in, the bottom of the well down into which the window slides as to prevent the window being completely opened so that there is always a portion of the window glass or of both the window glass and the sash in which it is'mounted projecting abovethe top of the well or above the lock rail at the bottomof the aperture which is to be closedv by the window The apparatus according to the present invention has been designed to. overcome the above mentioned objections as well as other objections incidental to the construction and arrangement of the previously proposed mechanism. i

The present invention therefore consists prinoipallyin a construction and arrangement of lazy tongs apparatus such that-the window glass, or the sash in which the window glass is fixed, is mounted ator ad jacent to the lower end or on thelowermost members or levers of the lazy tongs, while the top or uppermost members of the lazy tongs is or are mounted at or adjacent to the top of the window will in the door or. wall of the vehicle, so that when the window is moved downwardly to its open osition the lazy tongs is opened or expands and on the other hand when the window is moved to its closed position the lazy tongs is closed or collap'sech The present invention also comprises an improved construction and arrangementmf' gear or mechanism in conjunction with an operatinghandle for closing or collapsing and opening or expanding the lazy tongs so as to ctively close and open the window, the said mechanism being'also mounted to the top of the window well.

at or adjacent to the top of the window well in the door or wall of the vehicle.

Further in the construction of the apparatus according to this invention there is provided and mounted at the lower end of the main lazy tongs asecondary or smaller lazy tongs on whose upper levers or members the window glass,-or the lower transverse member of the sash in which the win-' dow glass is fitted,is mounted, this smaller lazy tongs being so operatively connected with the'main lazy tongs that when the'latter is closed or collapsed for the purpose of raising or closing the window the smaller lazy tongs is opened or expanded while when the main lazy tongs is opened or exbanded, for lowering or opening the window, the said smallerlazy tongs is closed or collapsed. suitable spring balancing means is also preferably provided. The lazy tongs apparatus itself may be also conveniently mounted on the said lock rail at or adjacent The gear or mechanism for actuating the lazy tongs comprises a pair of toothed wheels or sprocket wheels one of which is arranged so as to be rotatable by a suitable operating handle provided for actuating the lazy tongs so as to open and close the window. while the other sprocket wheel is rotatable on a suitable pivot or spindle and acts as a guide wheel for a suitable endless chain (which may be of the kind usually employed for drivingv cycles) which works on the said sprocket wheels, the said chain being operatively connected with the lazy tongs by means of a spindle or other suitable means.

Further, locking mechanism isprovided for locking or holding the operating handle of the lazy tongs apparatus in any desired position, thus also locking or holding the window in the desired position, the said locking means being such that a preliminary movement of the operating handle actuates a lock or catch so as to release or unlock the handle of the lazy tongs, while another movement of the operating handle will ac tuate the lazy tongs apparatus so as to open or close the window according to the direction of movement of the handle, and another movement of the said operating handle will cause or permit the lock to catch to be actuated so as to again lock the handle of the lazy tongs and consequently hold the window in the desired position.

Further features of the invention and details of construction will appear from the following description with reference to the a crmnanving draw-ingwhich illustrate appa a cordin to this invention.

Figs. 10 and 11 are side elevations partly in section of the operating handle and the locking means operatively connected therewith as hereinafter described. Fig. 12 is an elevation, looking in the direction of the arrows, Figs. 10 and 11, the operating handle being omitted. Figs. 13 and 14 are respectively front and side views of a portion of the sprocket chain showing means by which the chain is operatively connected to the main lazy tongs as hereinafter described. Figs. Fraud 16 are elevations showing the apparatus applied to the window of a railway carriage floor. Fig. 15 showing the window completely closed and Fig. 16 showing the window partly open. Fig. 17 is a plan view showing the method of mounting the apparatus on the crossbar or lock rail at the top of the window well in the door of a railway or other vehicle.

Like reference numbers indicate corresponding parts in the various figures of the drawings.

Referring first to Figs. 1 to 8 of the drawings, 1, 1 are the uppermost members or inner ends on the pins or pivots 4, 4 which in the example shown are secured to the easing or housing 5 which is suitably secured to a plate 6 adapted to be secured, for instance by means of screws through the flange 6", to a suitable support at or adjacent to the top of the well or recess, in the door or structure, into which the window slides when opened. As shown, the housing or casing is secured to the plate 6 by screws passing through flanges 7 and 8 on the housing 5 which may be a casting or may be made of sheet metal suitably cut and pressed to the desired form. The hereinbefore mentioned secondary or smaller lazy tongs comprises lower members or levers 9, 9* and upper members or levers 10, 10, the lower ends of the levers, 9, 9 being suitably secured to the lowermost members or levers, 2, 2 of the main lazytongs, for instance, as shown, the lower ends of the lovers 9, 9 of the smaller lazy tongs are fixed respectively to the lower end of the relatively short arms or plates 11, 11 the opposite ends of which are suitably fixed to the lower members or levers 2, 2 of the-main lazy tongs; the upper end of lever'9 is pivotally connected at 12 to the lower or outerendof lever 10, and the upper end of lever 9 is pivotall connected at 13 to the lower or outer en of lever 10. The upper or inner ends of levers 10 and 10 are pivotally connected together andhave mounted on them a suitable device by means of which the bottom of the window glass, or the bottom of the sash in which the window glass is mounted, can be attached to the levers or members 10, 10 of the smaller lazy tongs bracket or clip 14 is pivotally mounted on the pin or pivot 15 that connects the upper or inner ends of levers 10, 10, the said bracket 14 havin a projecting lug 16 by means of which t e window is attached to the smaller lazy tongs; the lug 16 engages between'depending lugs on a suitable part 17 (Fig. 15) secured to the bottom of the window glass or to the bottom of the sash in which the window glass is fitted, a transverse pin being passed through said lugs and the lug 16. 18 is the pin pivotally connecting the lowermost members or levers 2, 2 of the main lazy tongs together, and also pivotally connecting, at a position intermediate to their ends, the lower members or levers 9, 9* of the smaller or secondary lazy tongs. 19. (see F ig. 9) being'a'sleeve or ferrule on the pin 18 and between the levers 2, 2 of the main lazy tongs and the levers 9, 9 of the smaller lazy tongs.

'20 is a pin or pivot which operatively connects the intermediate levers or members, 3, 3 of the main lazy tongs to the sprocket chain 21, thesaid pin 20 being as shown (more clearly in Figs. 13 and 14) provided or formed on a plate or bar 21 which at each end is mounted on extensions of pivot pins 21, 21 that serve for connectin links of the chain 22 together. As clearlys own the pin 20 projects through holes provided centrally in the intermediate levers or members 3, 3" of the. main lazy tongs which levers may be In the example shown, a bifurcated held in engagement with the pivot 20 in any suitable manner for instance by means of a split pin passing through the pin or pivot 20;

23 and 24 (see Figs. 3 and 9) are the hereinbefore mentioned sprocket wheels on which the chain 22 works, 23 being the driving wheel through which movement is given to the chain 22, and, through the said chain and pin 20, to the lazy tongs apparatus. As clearly shown in'Fig. 9 the sprocket wheel 23 has tubular bosses which bear and revolve in opposite holes one of which is provided in .the plate 6 and the other in the housing or casing 5, and the sprocket wheel 24; is ro tatably mounted on a pivot or pin 25 the opposite ends of which are preferably fixed respectively in the plate 6 and housing or casing 5.

26 (see Figs. 1; 2 and 4) is a slot in the casing 5 through which the hereinbefore.

mentioned pin 20 projects and in which the said pin moves up and down as the chain 22 is actuated for raising and lowering the window. i

27 '(Figs. '7 and 8) are strips of leather or other suitable soft material arranged along the sides of the casing or housing 5 for the purpose of preventing objectionable noise which would occur if the-chain 22 could work against or come in contact with the metal housing 5.

Referring now to the handle for actuating the lazy tongs apparatus and the means for locking or holding said apparatus and the window in the desired position, 28 is a handle which is pivotally connected to the outer end of a spindle 29. The handle 28 as shown is of T shape but mav of course be of any other suitable shape. Further, in the examle'shown, the inner end of the handle 28 is ifureated so as to take on either side of the Outer end of the spindle 29 to which the handle is pivotally connected, for instance by a suitable pin 30, the spindle 29 as shown having a cross head 31, the arrangement being such that the handle 28 can be turned on the pivot 30 from the position shown in Fig. 10 down to the position shown in Fig. 11, or the handle 28 might be turned upward tothe opposite position to that shown in Fig. 11.

32 is a casing or housing, which may be a casting, adapted to be secured to the front or outside of the plate 6; for instance the casing 32 may have lugs 33 provided on it whereby the said casin late 6. lVithin the casing 32 is a disk 34 aving three or any suitable number of dowel pins or projections 35 formed or provided on its inner face the said disk 34 being may be screwed on to the capable of sliding inwardly and outwardly in the casing 32. y

36 is a hole bored centrally through the disk 34, and 37 is a spring which, at oneend bears on the outer face of the disk 34 and at its other end bears against the outer or front wall of the casing 32, the said spring tending to press the disk 34 upwardly from the position shown in Fig. 10 to the position shown in Fig. 11. .The disk 34 is secured on the s uare portion 295 of the spindle 29 by suitab e means, such for instance as a cross pin 30 in the spindle which projects through the hole 36 in the disk 34.

As clearly shown in Figs. 9, 10 and 11 the art 29- of the spindle 29 is rectangular in orm, or of other suitable shape, adapted to engage in the correspondingly shaped hole extending through the sprocket wheel 23 and through the bosses of the said wheel,'so that when the handle 28 is turned the spindle 29 will, through its rectangularor other su1tably shaped part, revolve the sprocket wheel 23 and so transmit motion .to the chain 22.

38 (Fig. 6) is an annular series of holes in the plate 6 with which the pins or projections 35 on the disk 34 are adapted to engage, 39 being a hole in the late 6 in which one boss of the sprocket w eel 23 engages and rotates. By connecting the inner ends of the uppermost members or levers 1, 1 of the main lazy tongs to the separate and respec= tive pivots or pins 4, 4 the overall depth or thickness of the apparatus, as measured from front to rear, is reduced to a minimum this being important owing to the confined space in which the apparatus has to be fitted or mounted.

40 is a known form of fiat balancing spring one end of which is coiled and mounted on the plate 41 suitably secured on one of the panels of the door, 42 being the usual roller mounted on the spring 40 and engaging with and working on the lower edge of the window or of the sash in which the window glass is mounted. The inner end of the coil of spring 40 is secured to a pin on plate 41.

The construction of the ap aratus is such that it can be very easily an quickly fitted in and removed from its position, for instance in the door of a railway carnage, motor car or other vehicle. As shown in Fi s. 15, 16 and 17, the cross bar (known as t e garnish rail or lock 43, at the to of the well or recess in the door into whic the window slides when opened, is cut across the middle so as to rovide a space of sufiicient size to receive lie plate 6, with housing 5 on which the various parts of the lazy tongs apparatus are mounted 44 being a steel or other suitable metal plate which is secured, for instance, by means of screws, to the outer face ofthe lock rail 43 a portion of this plate 44 beingcut away to accommodate the housing or casing 32 lnclosing locking mechanism as hereinbefore described. The plate 6 with the various parts attached can then be simply slid downwardly into the recess formed-bythe cut away portion of the lock rail 43 and the plate 44 attached to the said lock rail and the plate 6 is then secured, by two (or if desired more) screws passing through the flange 6* of the plate, to the to or upper edge of the lock rail 43. Should it be necessary to remove the apparatus, for instance for the purpose of examination or repairs, it is only necessary to remove the two screws from the flange 6" (the window lass being of course disconnected from the zy tongs apparatus and removed) when the whole 0 the apparatus can be very easily removed from the wall or recess in the door.

As shown in Figs. 1 and 2 the upper end of the arm or plate 11 is secured, for instance, as shown, by rivets, on the outer face or side (relatively to the plate 6) of the lever 2 of the main lazy tongs, the lower end of the said arm 11 being secured to the inner face or side of the lever 9 of the smaller lazy tongs; on the other hand the upper end of the arm or plate 11 is secured on the inner face or side of the lever 2 of the main lazy tongs, the lower end of the said arm 11 bemg secured to the inner side or face of the lever 9 of the smaller lazy tongs the said lower end of the arm 11 being suitably ofiset or cranked and secured to the end of the lever 9. A suitable spacing block or distance piece such as 11 (Fig. 1) may be in terposed between the end of the arm 11 and the end of the lever 9 to which the said arm is secured, for the purpose of reducing the cranking or set required in arm 11. Instead of the lower ends of the arms or plates 11, 11 being fixed, for instance by means of rivets as shown, to the lower ends of the levers 9, and 9 respectively of the smaller lazy tongs, the lower ends of the arms 11, 11 might, if desired, be pivotally connected with the lower ends of the said levers 9 and 9 respectively.

With the handle 28 and the disk 32 in the position shown in Figs. 9, and 10 the pro- JGBtlOIlS or pins 35 on the disk 34 are out of engagement with the holes 38 in the plate 6, the disk 34 being held, through the medium of the pin 30, in the position shown in these figures by the inner end of the handle 28 hearing against the outside of the casing 32 the spring 37 being then compressed. With the parts in this position the handle .28 can be turned in"one direction or the lazy tongsthus opening or closing the win-' dow according to the direction in which the said handle is turned. As hereinbefore mentioned when the main lazy tongs is closed or collapsed, in the action of raising or closing the window, the smaller or secondary lazy tongs is, through the arms 11 and 11 connecting the lower levers 9, 9' of the said smaller lazy tongs to the lowermost levers "2, 2 of the main lazy tongs, opened or extongs apparatus and consequently the win,

dow in any desired position, for instance a partly open position of the window, the handle 28 is turned on the pivot or pin 30 from the position shown.in the Figs. 9 and 10 to the position. shown in Fig. 11 (or equivalent positionl whereupon the spring 3-7 will expand so as to force the disk 34 outwardly from the position shown in Fig. 10 to the position shown in Fig. 11 in which position of the disk 34 the pins 35 thereon enter holes 38 (Fig. 6) in the plat 6 thus preventing further turning of the handle 28 and so holding the lazy tongs apparatus and the window in the desired position. To again release the handle 28 of the lazy tongs apparatus the said ha-ndle isagain turned from the position shown in Fig. 11 to the position shown in- Fig. .10 (or equivalent position) thus, through the pin 30' of the spindle 29,-

drawing the disk 34 inwardly in the casing thereby withdrawing the pins 35 from the holes 38 in the plate 6 and so unlocking the handle 28 of the lazy tongs apparatus which may then be again actuated for opening or closing the window.

Variations in and departures from the particulardetails of construction of certain parts of theapparatus as shown in the draw- 7. ingsmrgrtbe made without departing from the main features of the invention. For instance in place ,of the sprocket wheels 23 and 24 and chain 22 some other suitable means might be employed for actuating the lazy tongs; also some other suitable means for holding or locking the lazy tongs apparatus and the window in the desired position might be employed. Nevertheless I wish it to be understood that the mechanism for actuating the lazy tongs apparatus and for looking or holding the said apparatus and the window in the desired position as hereinbefore described and shown in the drawings has been proved in actual practice to be highly eflicient and satisfactdfv] Whatl claim as my invention and desire to secure by Letters Patent is 1.
